Description

Run "hdfs namenode -rollingUpgrade"

14/10/13 11:30:50 INFO namenode.NameNode: createNameNode [-rollingUpgrade]
14/10/13 11:30:50 FATAL namenode.NameNode: Exception in namenode join
java.lang.ArrayIndexOutOfBoundsException: 1

Although the command is illegal (missing rolling upgrade startup option), it should print a better error message.
